I bought these without looking closely enough at the package and was very disappointed to find really thick (about 1/16" v about 1mm) black nails with brass tops nails made to look like the strong thin German ones sold by Moore (also available at Utrecht Blick). The Ook ones will work for less critical applications but if you are hanging something important or heavy, go with the German-made originals, not these look-alikes. And given the fit and finish they should cost a lot less.
